Romankachi Friends !!!
Four of my friends Ashwath, Charan, Karthik and Srinivas are nicknamed Essi, KK, Kit and Maha, not necessarily in the same order.
My observations about them are as follows :-
1) Karthik is stronger than Essi but can't run as fast as Kit.
2) Essi is stronger than Ashwath but weaker than KK.
3) Srinivas is faster than Karthik and slower than Maha but weaker than Essi.
Can you recognize the nickname of each of my friends?

Answer
Ashwath is nicknamed Maha, Charan is nicknamed Essi, Karthik is nicknamed KK and Srinivas is nicknamed Kit.The observations given about the four friends are as follows :-
1) Karthik is stronger than Essi but can't run as fast as Kit.
2) Essi is stronger than Ashwath but weaker than KK.
3) Srinivas is faster than Karthik and slower than Maha but weaker than Essi.
From observation 1, Karthik is different from Essi and Kit. Hence Karthik may be any one of KK or Maha.
From observation 2, Ashwath is different from Essi and KK. Hence Ashwath may be any one of Kit or Maha.
From observation 3, Srinivas and Karthik are different from Maha and Essi. Hence they may be either KK or Kit.
Combining observations 2 and 3, Ashwath must be Maha, because Srinivas and Karthik are different from Maha and Essi and Ashwath is different from Essi, hence the only left out nickname for Ashwath being Maha.
Since Ashwath is Maha and using observation 3 (wherein Srinivas and Karthik are different from Maha and Essi), Charan is left with the nickname Essi.
From observation 3 we have, Srinivas and Karthik may be one of KK or Kit. However from observation 1, Karthik is different from Essi and Kit. Hence Karthik must be nicknamed KK and hence Srinivas is left with the nickname Kit.
Hence Ashwath, Charan, Karthik and Srinivas are nicknamed Maha, Essi, KK and Kit respectively.
